All the plants is ok now on my Vu4 installation But,in Vue3.1,the red coral always refuse to load,even i downloaded new file several times:is was ok with 3.0 but not with 3.1 and the same file red coral is ok now with version 4.I think is something with biosphere file:what exactly this file do?Now i have only biosphere4.dll but in Vue 3 i had biosphere3.dll,biosphere2.dll and biosphere1.dll Why each plant we buy there has a new biosphere file with it?
